I tried ProGuard many times and spent a lot of time setting it up to no avail last year or so. It seems to have some inherent limitations associated with precompiled third-party libraries, as described in his document. The ProGuard document perfectly provides a long list of alternatives . Instead of trying them one by one, I am here to find out if anyone can share successful experiences with some of them. I only need something to confuse Java code. Speeding up and optimizing the code is good, but not required.
